藥芯焊絲焊接時(shí)比CO2實(shí)芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實(shí)芯焊絲飛濺大小的比較。焊接質(zhì)量好一般CO2實(shí)芯焊絲只適合于低碳鋼或強(qiáng)度級(jí)別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結(jié)構(gòu)鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實(shí)芯焊絲有了很大的提高，可適用于各種重要結(jié)構(gòu)的焊接，而CO2實(shí)芯焊絲一般只用于0度以上工作的一般鋼結(jié)構(gòu)。綜合焊接成本：低藥芯焊絲相對(duì)價(jià)格較高，但其綜合生產(chǎn)成本比焊條電弧焊要低許多，與CO2實(shí)芯焊絲大體相當(dāng)。藥芯焊絲的型號(hào)及牌號(hào)按GB10045—88規(guī)怎定，藥芯焊絲***部分以英文字母“EF”表示藥芯焊絲代號(hào)，代號(hào)后面的***位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號(hào)后面的第二位數(shù)字或英文字母為分類代號(hào)。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學(xué)性能。如焊絲型號(hào)EF03-5042。實(shí)際生產(chǎn)中還經(jīng)常用牌號(hào)來(lái)表示藥芯焊絲的類型。藥芯焊絲生產(chǎn)牌號(hào)用如下符號(hào)表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類，***、第二位數(shù)字表示焊絲特點(diǎn)；第三位數(shù)字表示溶渣類型（或第三位以后之?dāng)?shù)字及元素符號(hào)表示焊縫金屬化學(xué)成分）。</p><p> co2氣保焊從不會(huì)到精通一、焊接開(kāi)始先打開(kāi)配電盤開(kāi)關(guān)，再打開(kāi)焊機(jī)電源開(kāi)關(guān)。（注意：再打開(kāi)電源開(kāi)關(guān)時(shí)，應(yīng)側(cè)身操作，避免因電器短路造成燒傷等）。緩慢打開(kāi)儲(chǔ)氣瓶閥門。調(diào)節(jié)合適的氣壓。調(diào)節(jié)合適的電流，電壓。二、焊接結(jié)束關(guān)閉儲(chǔ)氣瓶閥門，放出氣管內(nèi)殘留氣體。然后關(guān)閉電源。把設(shè)備整理好放回原處。三、焊絲盤的安裝選擇合適的焊絲直徑。向焊絲盤軸裝焊絲盤，并固定牢固。將焊絲插入焊絲插口處。用焊絲加壓手柄給焊絲施加合適的壓力。選擇合適的導(dǎo)電嘴，并擰緊。四、焊操作基礎(chǔ)1.引弧及焊接完成時(shí)的操作:因?yàn)橐〖昂附油瓿蓵r(shí)容易出現(xiàn)缺點(diǎn)，所以操作焊時(shí)一定要遵守噴嘴-工件間距離及焊角度。在引弧前的間隔，受到焊絲接觸時(shí)的沖擊而回升，注意勿使焊因沖擊而回升。2.噴嘴-工件間距離：噴嘴-工件間距離過(guò)大時(shí)，容易產(chǎn)生缺點(diǎn)（氣孔，坑等）。一般情況下采用焊絲直徑的10倍距離左右（如焊絲，選用距離為10毫米左右）。3.導(dǎo)電嘴距離噴嘴外緣5mm比較好。4.氣體保護(hù)效果不好的識(shí)別：根據(jù)電弧聲音及熔池狀態(tài)等就可以很簡(jiǎn)單地判斷正常電弧，異常電弧時(shí)的熔池成沸騰狀，需經(jīng)過(guò)經(jīng)驗(yàn)來(lái)掌握正常電弧的狀態(tài)。5.焊絲伸出長(zhǎng)度的影響：導(dǎo)電嘴-母材間距離過(guò)長(zhǎng)時(shí)，影響有：產(chǎn)生氣孔。?二氧化碳?xì)怏w保護(hù)電弧焊（簡(jiǎn)稱CO2焊）的保護(hù)氣體是二氧化碳（有時(shí)采用CO2+O2的混合氣體）。</p><div
